The invention describes a device used to measure the tension of a soft tissue 24 attached to bones 20,22. The device 2 comprises a body region 4 having force applying hook shaft 6a and abutment spike shaft 8a extending outwardly therefrom. A spike region 8b of the abutment spike shaft 8a is extended in direction X to thereby abut the surface of bone 22. The force of the abutment is measurable by a displacement on a translation scale 14. An operator pulls on the device 2 in direction Y thereby applying an anterior force (measured by a displacement on a force scale 14) to the tissue 24 via a hook region 6b of the force applying hook shaft 6a. The application of said anterior force on to the tissue 24 results in an anterior translation of the tissue 24. The tension of the tissue 24 may be calculated from the displacements on the force scale 12 and translation scale 14.
